His name was Thomas Arthur Vallee. He had made open and loud threats that he would assassinate Kennedy. The Secret Service only picked him up when Kennedy canceled his trip to Chicago at 10:00 a.m. What one finds in Vallee and the whole Chicago plot are so many similarities to what happened in Dallas later that month.Vallee, if we compare him to Oswald, is an ex-Marine. He had been posted, like Oswald, in the far east on a station that was linked to the CIA. It was easy to portray him as disgruntled, anti-Kennedy, a loner, and armed.Vallee trained Cuban exiles for combat, which was a CIA responsibility. We know Oswald wanted to do the same and he most likely did.Oswald was moved from New Orleans to Dallas just a month before the assassination. He was placed, and given a job in a tall building. It was a perfect killzone.Vallee was also moved around like a pawn. He was moved just a few months prior from Long Island to Chicago just in time for the plot. Where does he get a job? In a tall building, adjacent to the motorcade, with the perfect killzone view. It would have forced Kennedy’s motorcade to do a sharp turn, slow down, and result in a perfect point where they would have had perfect triangulation of fire, just like in Dallas.To eliminate their own President, with the help of the Dallas police and their media assets, would be a low-risk operation.Shortly after John Kennedy’s arrival in Dallas, amid massive outpourings of affection, despite signs vilifying him posted along the way, and an FBI airtel informing Hoover of a possible assassination attempt that day, another warning came from the CIA’s George Bush of yet another potential attempt. He was seated in his limousine, which had no bubble top. It had been conveniently removed at the order of Bill Moyers, then a press aide to Lyndon Johnson.Security was surprisingly lax. Just before leaving Love Field, a cameraman caught footage of Secret Service Chief Emory Roberts ordering his agents off the President's limousine as it began its approach toward Dealey Plaza. Originally scheduled to travel down Main Street through the Plaza, the motorcade route was changed at the last minute. The new route turned left on Elm, toward the Book Depository, a move that violated all Secret Service protocols for the protection of a President.Not only was this route leading them into an ambush, but it also passed by the building in which they had planted the patsy. They were moving unusually slow as they passed the Depository, the target zone, going only eleven miles per hour, which is nearly stationary for professionals with rifles prepared to take their shots.Abraham Zapruder, a clothing manufacturer, had taken the afternoon off to film the President. In moments, gunshots would ring out at 12:30pm. Zapruder's film would become the most famous and suppressed piece of evidence in human history. Jackie Kennedy is seen scrambling over the back seat to retrieve part of her husband’s brain. Motorcycle officer Billy Hargis, riding to the left rear, was splattered with blood and brain tissue.
